specification of Lettersratent No; 26,317, dated November 129,]5118519.

To all whom it may concern:

Be it known that I, MARTIN WINGER, of Vogansville, in the county ofLancasterand State of Pennsylvania, have invented a new and usefulmachine for the purpose of shaving off the rough crust or epidermisfrom` oak-bark, preparatory to the manufacture of` quercitron, used andexported vfor dyeing purposes; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, in which- 1 Figure 1, is aperspective view of the entire machine. Fig. 2: Nos. 1, 2 and 4; the

three concave sided cast iron rollers, de-1 tached, No. 3, the curvedknives mounted on 'rollers aflixed to the axis which bears the strappulleys D, C. T is the adjust-ing fra-me. Fig. 3 is an end View` of Fig.6.

Fig. 4 shows the sliding frame G, the slides X, and grooved or slotteduprights F, fixed to the side frame Z of the machine, with the bearingpulley It, mounted in the vertical shaft H. Fig. 5, is one of the curvedshaving knives V: Fig. 6, a side view of the `broad belt WV of leatherto which the planoconvex cross pieces O, O, are attached forming anendless platform around the flanged outside drums Q with intermediatesmalll carrying rollers, P, and a central flanged gulding roller P, asshown. Power, by means of a horse or steam is applied to the largerstrap pulley D, the

shaft of which supports and revolves the shaving drum No. 3. There isalso a smaller" strap pulley C, on this shaft, connected by a `strap tothe larger pulley B. Behind this pulley B on its shaft is a smallcogwheel (not seen but traced on the drawing) geared into a largeco-gwheel on the shaft of the front flanged drum Q which gives motion tothe endless revolving platform O, O, W.

The operation is thus: The bark of any size or thickness is laid withits concaved side upon the convex portion of the platform O,

which conveys it under the heavy pressing` roller l, so fixed in theuprights E, as to giveit play and accommodate itself to `they() 1 bark,however thick, This roller presses` the.. `bark of a regular curve onthe` endless] plat` foi-m, which hasshortjretaining pegs in ea"` n .lpiece, that enter the fiber? orginside"offftljelI bark. There is,between 1 this andthe con`` "ducting rollerV 2, `agbearing,pulleyflnasstated, supported on the" vertical shaftyHto prevent the possibility`ofthe bark from tur l ing upward as itpasseswthrough"underthe lpressing roller `1,1 to; the@ conducting "roller "No 2, which latterpresents it tothe action l of a series of knives V, mounted as shown by`1.11

1 No. 3, Fig. 2. 1 These mounted knivesyhave;l their axes supported" inthe "frame T, inside: 1 V the external fraineIQslotted so astolallowj",` the shaft or axis tdmove up and down. On` the top of theframe T, are two squareghead-" ed screws N, surinountedbytfcoggedpulleys, .l M, geared into a cogged wheellL, on top lS, .1 l, of theupright I. `"Thescrewsfenter,fenialefo y screws in the top V, oftheuprights K, and

thus by moving the `wheel L, the knives can be raised and lowered, toadapt themto; the n .i diverse thicknesses, in thefpieces of bark tol``y@ l be operated on. The convex; platform*v 0,275.1 O, W, is adapted tothe natural concavityzof 3 n i the bark, thereby 1 preventing itssplitting n when pressed into a uniform` curve, to which 1 the knivesare also adaptedaso thattliisf machine can `performtliegworkofp`niany"8f01 hands when employedinthe ordinaryman-p` l., ,1 nerwithdrawing knivesas is customary. 11 y, 1 Machines may `liavewbeenused, to`3pr`ess j bark fiat and shavefthem, and in somerespects perhapssimilar inconstruction.` f C y I do not simply1 claim the pressingand^`1 l shaving by machinery nor thegearing ein-f` j, ployed separatelyconsidered.` 1i f y What Iclaim asmyinvention and `desire j y; to secureby Letters Patent isf-f l Jj@ 111 F9() `l The combination of the convextraveling bed O, W,`with thefrotary knives V,and`1 pressure rollers l, 24 and L` inthe uTanner1,` and for thepurpose setl forth.
